Here is the code...
CODE
<script language="javascript">
<!--//
/*This Script allows people to enter by using a form that asks for a
UserID and Password*/
function pasuser(form) {
if (form.id.value=="asta") {
if (form.pass.value=="host") {
location="page2.html"
} else {
alert("Invalid Password")
}
} else { alert("Invalid UserID")
}
}
//-->
</script>
<center>
<table bgcolor="white" cellpadding="12" border="1">
<tr><td colspan="2"><center><h1><i><b>Login
Area</b></i></h1></center></td></tr>
<tr><td><h1><i><b>UserID:</b></i></h1></td><td><form
name="login"><input
name="id" type="text"></td></tr>
<tr><td><h1><i><b>Password:</b></i></h1></td><td><input

Your username and password can be viewed from the source code of your page, just to make it more secure, encrypt.
And now, if you are thinking "How am I going to encrypt a page?", visit this page (http://www.cyberiapc.com/aascripter/samples/Security/sub9.htm), over here you just have to paste your java script code and it will encrypt it for you.
On this page you can even give it an encrypted code and it will decrypt it for you (bring it back to its original state). Thus the above script must not be used for anything serious.
If you plan to go and hide something more serious try, Bravenet.com service which is much, much secure, its just like loging into your email ID (yahoo or hotmail).
anyone, even unexperienced can brake it and "login" or see the content, the only place I might of think is to integrate it with xml and send a http request, yes to use AJAX.
